him always had a classic seasoning — Greek as well as Botany — which 

 made them doubly enjoyable ; while his genial charity toward all 

 men was a pattern and delight/* And from one other : *' We had 

 been friends for more than forty years * * * a more pure- 

 minded and true-hearted man I have never known, * * * The 

 world has lost in him a profound classical scholar, a most conscien- 

 tious teacher, and an enthusiastic botanist." 



We shall close this brief biographical notice with one more extract 

 from a letter of this old friend, touching in its sadness: ''Our dear 

 departed friend has left an aching void in the hearts of all who knew 

 him, so kindly disposed and sincere in his affections he was, while 

 gifted with extraordinaty powers of promoting innocent mirth and 

 true sociality. One cannot expect to meet with many such in a life- 

 time. Would he had been spared to us many years longer. I little 

 thought 1 should outlive him." 



A New Species of Dichromena. 



By S. H. Wright. 



T. H. 



Dichromena Reverchoni. — Culm nearly terete, smooth, slen- 

 der, caespitose, four to nine inches high ; leaves very narrow, 

 smooth, acute, almost capillary, those of the culm i| to 2^ inches 

 long ; radical leaves 2 to 5 inches long, dtect or falcate and spread- 

 ing; involucre of two slender, unequal, acute bracts, dilated and 

 whitened at the base, the longer being about i inch in length, and 

 the shorter from ^ to ^ inch long ; spikes 4 to 6, and i to i inch long, 

 terminal, sessile, glomerate, scales variable, acute, obtuse, truncate, 

 or even eniarginate in the same spike, and keeled, white, with more or 

 less ferruginous lines at the base when mature; achenia dull, strongly 

 rugose, round-obovate, very convex, the dilated base of the short- 

 beaked, compressed tubercle, decurrent on both edges to and 

 around the base of the nut, giving it an annulated appearance there. 



This species was discovered in 1879, and in one place only, by 

 Mr. Julien Reverchon in a little swamp watered by a spring in lime- 

 stone rocks, near Turtle Creek, Dallas County, Texas, and near 

 Dallas. It flowered in June. Specimens collected in 1880. in flower 

 only, were sent to me. A very few in fruit, collected in 1881, were 

 obtained, from which the above description is given.
